sel for holding an aqueous electrolyte,

a molded dome of dielectric material disposed over said vessel invaporsteam, and a metal plug comrnunicat` ing between said interior ofthe container well and the i11- terior of said dome, whereby heat fromthe dome-confined steam heats said plug thereby heating vaporizablemedicant disposed in said container well.

2. A thermally controlled vaporizer medicated vapors comprising anupright vessel for holding an aqueous electrolyte, a plastic domedisposed over said vessel in vapor-tight manner and having a verticallydisposed medicant container well therein, a cylindrical verticallydisposed vaporization plastic well secured to said dome in vapor-tightrelation and disposed in said electrolyte and having an orifice in itsbase for passage of electrolyte from said vessel into said well, heatingrods secured to said dome and immersed in said electrolyte in said wellfor changing water into steam, and a disc valve having a plurality oflegs oatably disposed in the bottom of said vaporization wellintermediate the bottom of said electrodes and the orice disposed in thebase of said well, whereby the ease of introducing electrolyte solutionabove the valve in said well is greater than that of forcing out saidsolution by steam formed in said vaporization well.

3. A thermally controlled electrically heated vaporizer for vaporizingmedicated liquid comprising an upright vessel for holding an aqueouselectrolyte, a dome of insulating dielectric material disposed over saidvessel and having an upright container well integrally molded therein, acylindrical vertically disposed vaporlzation Well of for dispersingplastic material secured to said dome in vapor-tight relation anddisposed in said electrolyte and having an orijce in its base forpassage of electrolyte from said vessel into the vaporization well,electrically heating rods secured to said dome and disposed verticallyin said electrolyte in said vaporization well for changing water intosteam, a metal plug communicating between the interior of the containerwell and the interior of said dome, a metal container disposed in saidcontainer well and upon said plug, and a displaceable valve disc havinga plurality of spacer legs oatably disposed in said vaporization wellintermediate the bottom of said electrodes and the oriice disposed inthe base of said Well, whereby medicated liquid disposed in saidcontainer is continuously heated by said plug which in turn is heated bythe steam confined in said dome and the ow of electrolyte solution intosaid vaporization well is continuous for continuous formation of steamwithout eiecting a back pressure upon the surface of the electrolytelocated in the vaporization well'.
